Common Phase Error Correction for OFDM in Wireless Communication
Overview Orthogonal Frequency Division Multiplex (OFDM) systems are very sensitive to phase noise caused by oscillator instabilities. In this paper the phase noise is resolved into two components, namely the Common Phase Error (CPE), which affects all the subchannels equally and the Inter Carrier Interference (ICI), which is caused by the loss of orthogonality of the subcarriers. The paper presents a technique to estimate and correct the CPE component and demonstrates its effectiveness when applied to a Broadband Fixed Wireless Access (BFWA) data transmission system for the Multichannel Multipoint Distribution Service (MMDS) band.
